yes, a combination of Ocean/Lusty and AH-64, with SSN/TLAM and T45 could theoretically be used to attack the islands. given however that the Argentines would have occupancy of MPA, and would doubtlessly be using it to operate some of its 64 fast jets (Mirage III, V, IAI Dagger, A-4AR and Super Etendard) - what kind of casualty rate do you think this 'oxfam' fleet would take before a set of gucci goretex boots walked on the sand?
